The best thing about Destiny Student - Cowgate was definitely the location for Fringe. Very central, close to a lot of venues and High Street, and a 10min walk from the train station.
The room was... odd. The lights for the entire studio were either all on or all off. Not great for relaxing in bed before falling asleep. There were also no instructions regarding how to turn on the tv (no combination of buttons on the two remotes or the tv itself seemed to do the trick), and the fan above the cooktop didn't work. The pillowcases and duvet on the bed did not look clean when I arrived (hairs and other dirt were visible), and one evening I came home to find a dead mouse on the floor! When I called the front desk (from my cell phone, as the phone on the wall did not seem to work), the person who came up did not seem to know what to do about the mouse. Lastly, the dishes in the cabinet were -mostly-clean, as if someone had done a sort of decent job of hand washing them. Considering there's a dishwasher in the studio I'm surprised the housekeeping staff doesn't do a load between guests.
All that being said, the bathroom was clean, the building felt safe, there was inexpensive laundry in the basement, and the location was PERFECT.
